Hi
I am outside observing and its going great and then all of a sudden the garden light turns on right in front of the telescope so I had to go get a
towel from inside and put the towel over the lightbut it was a windy night so It kept blowing of I had nothing to stick down with so I packed up not light pollution BUt it made me think how much light can ruin observing
good luck to ya all out there and as I say turn of that god dam [size=6]LIGHT[/size]

I specifically changed ours to a PIR bulk head light that is on a switched fused spur so I can easily turn it off. The garden flood lights are on manual switches and rarely get used. On the other hand, my neighbour turns his flood light on to let his dogs out for toilet before going to bed, which in winter can be right in the middle of an observing session! Ahhhh!
